DW-3315 Intelligent Infrared Sound Reinforcement System
The DW-3315 combines multimodal AI audio processing with infrared wireless reception and a quasi-digital amplifier. Six or more built-in microphones provide at least 8 metres of pickup, with automatic feedback, noise and echo control.
- Multimodal AI audio processing combines automatic feedback suppression (AFC), noise suppression (ANS), echo cancellation (AEC), automatic gain control (AGC) and reverb suppression (ARR).
- Infrared wireless reception, quasi-digital amplification and a high-definition rotary knob display are integrated into one system.
- Infrared and wired microphones share priority with millisecond-level AI switching, so there are no audio interruptions when the teacher moves between sources.
Overview
Key features
- Multimodal AI audio processing combines automatic feedback suppression (AFC), noise suppression (ANS), echo cancellation (AEC), automatic gain control (AGC) and reverb suppression (ARR).
- Infrared wireless reception, quasi-digital amplification and a high-definition rotary knob display are integrated into one system.
- Infrared and wired microphones share priority with millisecond-level AI switching, so there are no audio interruptions when the teacher moves between sources.
- Automatic acoustic adaptation — no manual tuning is required when the system is installed in a new room.
- Six or more built-in microphones deliver an effective pickup range of at least 8 metres.
- A configurable sound barrier wall (180° or 360°) separates podium and student-area audio for focused pickup.
- Built-in digital sound card and RS-232 serial control support recording, video-conference platforms and room automation.
The DW-3315 is an intelligent infrared sound reinforcement system for classrooms where clear speech matters more than volume. Its multimodal AI processing continuously manages feedback, background noise, echo, gain and reverb, so the teacher's voice stays intelligible without manual EQ or volume adjustments.
The system brings together an infrared wireless receiver, a quasi-digital power amplifier and a high-definition rotary knob display in one unit. Six or more built-in microphones cover an effective pickup range of at least eight metres, while the configurable sound barrier wall can be set to 180° or 360° to separate podium audio from the student area.
Audio that adapts to the room
- No commissioning skills required — the system analyses the acoustic environment on installation and adapts its processing automatically.
- Seamless source switching — infrared and wired microphones share priority with millisecond-level switching, avoiding dropouts when the teacher moves between a pendant microphone and a podium microphone.
- Hybrid teaching built in — the digital sound card lets the system feed recording software and video-conference platforms without an external audio interface.
- Room automation ready — RS-232 control allows integration with central control systems and campus management platforms.
The DW-3315 is suited to primary and secondary classrooms, lecture halls, training centres and hybrid-teaching rooms. It can be supplied as a complete kit with speakers, charging dock and microphones, or configured for an existing room.

Frequently Asked Questions
Which rooms is the DW-3315 designed for?
The DW-3315 is typically installed in classroom, lecture hall, podium, hybrid teaching. Room size, ceiling height and speaker layout determine the final configuration — send us a floor plan and our team will recommend a layout.
What coverage does the DW-3315 provide?
The rated coverage is ≥ 8 m. Infrared coverage depends on sensor placement and room geometry; an expansion sensor can be added where the room has shadowed areas.
Does the DW-3315 work with hybrid and online teaching?
Yes. The DW-3315 includes a built-in digital audio interface, so it can feed a classroom PC, lecture-capture recorder or video-conference platform without an external sound card.
What certifications and warranty are available for the DW-3315?
Seekika Audio supplies CE, RoHS and FCC compliance documentation for its classroom audio products. Classroom audio products carry a standard 2-year warranty against manufacturing defects, with extended coverage available on project orders.
